I recently created a quiz on Sporcle, a free site with quizzes on everything under the sun.
I linked the quiz below. It's actually closer to a Herculean task. You must list every named character to pass through the YJ television show, the comic, and the video game, along with three of the most important characters revealed to exist by Greg Weisman.
Given that I couldn't get 100% on this immediately after I completed it, with all the names still swirling about in my head, I don't think it is possible. (But Tupka will probably prove me wrong first go.) There is also one based on Gargoyles, if you are interested (not created by me).
ALSO!! Should I add a third column with a hint of some kind? Maybe team affiliation, race, something??
